When I started to play with OCaml I was kind of surprised that there was no id (identity) function that was available out-of-box (in Stdlib module, that’s auto-opened). A quick search led me to the Fun module, which is part of the standard library and is nested under Stdlib.
Today I’m going to cover a very basic topic - conversions between OCaml’s primary numeric types int and float. I guess most of you are wondering if such a basic topic deserves a special treatment, but if you read on I promise that it will be worth it.
Jon asked me to make a Docker image that contains OxCaml ready to run without the need to build it from scratch.

Earlier this year, I returned to the Computer Laboratory at the University of Cambridge, as part of the Energy and Environment Group, combining with my work at Tarides.
